Bodies have zero mass by default, therefore they are static by default.
如果物体定义为零质量，那么它的默认状态就是静态的。
The ground is a box that is static, which Box2D knows, because the box has zero mass (by default) and therefore doesn't collide with other objects.
地面是一个静止的立方体，这是Box2D已知的，因为这个立方体的质量为零(默认)，因此不会与其他物体相撞。
I will set them again to zero and now we get one onto double the mass.
我们将它重新调零，再放一个让质量增倍。
